13. Study of kidney morphologic and structural changes related to different ischemia times and types of clamping of the renal vascular pedicle
ABSTRACT Purpose This study aimed to study morphological and renal structural changes in relation to different ischemic times and types of renal vascular pedicle clamping. Methods Sixteen pigs were divided into two groups (n = 8): Group AV - unilateral clamping of the renal artery and vein and Group A - unilateral clamping of the renal artery only, both

14. Optimized design of RC deep beams based on performance metrics applied to strut and tie model and in-plane stress conditions
Abstract Deep beams do not behave according to classical beam theory. The nonlinearity of strain distribution within these elements requires application of strut and tie models (STM) or other alternatives to evaluate the complex stress field. Although the design of these elements is a common task for structural engineers, limited research is found on assessi

16. Enhancement the Fatigue Life of Floating Breakwater Mooring System Using Tuned Liquid Column Damper
Abstract Safety is a key design criterion for floating structures. A high rate of mooring accidents has been reported over the past decades. Preventing mooring line failure is a key design objective for floating breakwater systems. The mooring system comprises sets of mooring lines anchored to the seabed. These components are exposed to highly cyclic nonline

17. Application of Support Vector Machine and Finite Element Method to predict the mechanical properties of concrete
Abstract Compressive strength and Young’s modulus are the main properties used in the design of concrete structures. They are responsible for the cost, safety and dimensioning of the structure, and are generally measured in expensive and time-demanding tests. This fact encourages researches for fast and cost-effective methods to investigate the concrete’

18. Analysis of the contribution of the block-soil contact in piled foundations
Abstract Geotechnical engineering has often been challenged by demands from technically and economically bold construction projects, such as that of tall buildings. The architectural requirements of these buildings have increased and concentrated the loads from structural systems without proportionally increasing plant area. New forms of using load capacity

19. Reliability analysis of built concrete dam
Resumo O projeto convencional de barragens de gravidade de concreto ainda segue o método determinístico, que não quantifica diretamente o efeito das incertezas na segurança da estrutura. A teoria de confiabilidade estrutural permite a quantificação da segurança destas estruturas, a partir da quantificação das incertezas inerentes aos parâmetros de

21. Ultimate bending capacity of aged fixed platform by considering the effect of marine fouling
Abstract For offshore structures, especially jacket supported structure such as fixed platform and offshore wind turbine, the underwater area provides an ideal site for corrosion formation and marine fouling. In this marine environment, the structures are exposed to particularly aggressive corrosion and colonized by marine organisms involving a diversity of

22. Dynamic structural response characteristics of new concept blast walls under hydrocarbon explosions
Abstract Offshore installations activities entail the hazard of explosion accidents with potentially severe consequences to safety of workers, integrity of system, pollution of the environment, and economic losses. Blast walls are generally used for the purpose of reducing the explosion consequences. This study introduce a new concept of blast wall (perforat

23. ESTIMATION OF THE CHARACTERISTIC VALUE OF WOOD STRENGTH
ABSTRACT For safety reasons, wood strength values, essential for structural dimensioning, are calculated based on the characteristic value, which corresponds to the 5% percentile of a given probability distribution model. For small samples, the Brazilian normative document ABNT NBR 7190 establishes an estimator of the characteristic wood strength, which can

24. Strut-and-tie models for linear and nonlinear behavior of concrete based on topological evolutionary structure optimization (ESO)
Resumo A busca por sistemas resistentes representativos para estrutura de concreto requer profundo conhecimento sobre seu comportamento mecânico. Os modelos de bielas e tirantes são procedimentos clássicos utilizados no dimensionamento do concreto armado onde existem concentrações de tensão, as chamadas regiões descontínuas da estrutura. No entanto,
